We have a LAN with the network license on the C: drive of a shared computer. When a deployment tries to open Civil 3D, the "error (-15.570.0) unable to access license, valid license cannot be obtained by the network license manager" occurs.
The two computers can ping to each other, we've added permission to the autodesk license manager through the firewalls. Both computers are Windows 7 Professional.
Civil 3D opens on the computer that holds the network license. Where do we start?
